That swap could cut the energy required for memory switching by up to two orders of magnitude, the paper claims. Study author Dr. Elton J.G. Santos says the same underlying framework could extend to electrical currents and ultrafast laser pulses, two other technologies being explored for future data storage. The work is currently theoretical, but the authors outlined practical steps other labs could use to build prototypes and run experiments.\n\nData center energy use has become one of the most visible costs of the AI boom, with communities near new builds increasingly pushing back. Memory and storage are a persistent drain in that math, so a switching method that approaches thermodynamic efficiency limits targets a bottleneck that faster chips alone can't solve.\n\nIt's a promising lab result with a long road ahead, and claims of \"orders of magnitude\" efficiency gains have a habit of shrinking once engineers try to build the real thing.","[\"ai\",\"hardware\",\"energy\",\"research\"]","2026-09-07T19:00:00.000Z","2026-09-07T20:10:24.580Z","2026-09-07T20:10:36.423Z","published",null,[],"science",[26,27,28,29],"ai","hardware","energy","research",[31],{"name":32,"url":33},"TechRadar","https:\u002F\u002Fwww.techradar.com\u002Fcomputing\u002Fscientists-develop-ultrafast-magnetic-field-pulses-memory-system-that-could-cut-ai-data-center-energy-use-by-100x-and-even-get-close-to-hitting-thermodynamic-limits",0,{"sections":36},[37,41,46,51,56,60,65,67,72,77,82,87,92,97],{"name":38,"slug":26,"count":39,"latest_published_at":40},"AI",3415,"2026-09-07T18:24:32.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",583,"2026-09-07T23:05:51.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Policy","policy",313,"2026-09-07T15:41:19.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":57,"slug":27,"count":58,"latest_published_at":59},"Hardware",152,"2026-09-03T09:26:48.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",97,"2026-09-04T15:29:18.000Z",{"name":66,"slug":24,"count":63,"latest_published_at":18},"Science",{"name":68,"slug":69,"count":70,"latest_published_at":71},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":73,"slug":74,"count":75,"latest_published_at":76},"Dev Tools","dev-tools",69,"2026-08-18T04:00:00.000Z",{"name":78,"slug":79,"count":80,"latest_published_at":81},"Startups","startups",54,"2026-09-04T23:36:14.000Z",{"name":83,"slug":84,"count":85,"latest_published_at":86},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":88,"slug":89,"count":90,"latest_published_at":91},"General","general",40,"2026-09-07T08:57:14.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
